Abstract: A stabilizing ability, so-called stability, according to a change in body motion of a wearer is to be appropriately evaluated to achieve effective training, coaching, and fitting of athletic equipment.

Abstract: Display and output are performed in such a manner as to allow complex body motions to be comprehended instantaneously. There are provided: a plurality of body motion sensors 40 which are worn on a wearer's 1 parts subject to cyclic motions and which are capable of measuring three-dimensional displacements and accelerations at the respective parts; a memory 114 which records detection results as body motion data; a cycle extraction unit 170c which extracts a cyclic motion of each of the body motion sensors 40 on the basis of accumulated body motion data; an analysis unit 170d which analyzes the characteristic of a change in angular velocity in the extracted cyclic motion; and displays 100a, 100b that display or output the characteristic analyzed by the analysis unit 170d in association with the rotation angle of the cyclic motion extracted by the cycle extraction unit 170c.

Abstract: To allow combining devices having different functions according to an application, and improve convenience for a user. There are provided a wearing type terminal 1 provided with an external case 10 having a display unit 131 on the upper surface side and belt members 4a and 4b which can be connected to the both sides of the external case 10 respectively; and a docking type device 2 which is detachably engaged with the bottom portion of the external case 10 of the wearing type terminal 1, and is electrically connected to the wearing type terminal 1 via a dock side connection terminal 21. The wearing type terminal 1 and the docking type device 2 are provided with a function which carries out transmission and receiving of data to be displayed on the display unit 131 via the dock side connection terminal 21.
